Prince Jean Marie François Ferdinand de Broglie (21 June 1921 – 24 December 1976) was a French politician.
Born in Paris, he was one of the negotiators of the Évian Accords.
Jean de Broglie was assassinated on 24 December 1976 while coming out of the house of Pierre de Varga, his financial advisor. Varga was quickly arrested; in 1981, he was sentenced to ten years imprisonment for complicity in the assassination.
Jean de Broglie was the first son of Prince Eugene Marie Amédée de Broglie (1891–1957), himself the fourth son of Prince François Marie Albert de Broglie (1851–1939), himself the fourth son of Albert de Broglie, 4th duc de Broglie, whose mother, Albertine de Staël-Holstein (1797–1838), was the daughter of Germaine de Staël and, reputedly, Benjamin Constant.
By his wife Micheline Segard (1925–1997), he had three sons:
- Victor-François de Broglie (Paris, 25 March 1949 - Broglie, 12 February 2012), 8th duke of Broglie, who succeeded a distinguished distant cousin, Louis de Broglie, 7th duke of Broglie (1892–1987), physicist and Nobel laureate
- Philippe-Maurice de Broglie (Paris, 28 September 1960), 9th duke of Broglie
- Louis-Albert de Broglie (Paris, 15 March 1963), prince of Broglie
